Research hypothesis:
– Nitrate accumulation = low light level – Optimized photosynthesis light spectrum – Minimize nitrate in irrigation – Pre-harvest light recipe to accelerate nitrate reductase

Vitamin C (mg/kg)
When grown in the greenhouse, tomato fruit typically have low levels of vitamin C. Light is the major regulatory of plants vitamin C content. Increases of more than 30 % is observed after illuminating the detached fruits with LED lighting.

Shelf life test are being done at the moment and are showing some differences depending
handling. Light level before harvest is very important for shelf life and overall visual quality.

Vertical farming enables control of all the growth parameters Yield, Quality and Nutrient are controlled
this is a revolution in food production Eating fresh, locally grown, healthy vegetables, pesticides free, all year long will transform the food chain and impact human health
